Audio data processing device and processing method

Abstract

The invention discloses an audio data processing device and method. The processing device is simultaneously arranged at a sender A and a receiver B. The processing device comprises an SM2 module, an SM3 module, an SM4 module, a microcontroller and a communication module. The SM2 module is used for generating a public key and a private key, performing encryption and decryption, and performing signature verification; the SM3 module is used for verifying data integrity; the SM4 module is used for encrypting and decrypting the audio data; the communication module is used for data transmission between the sender A and the receiver B; and the controller of the receiver B calls the SM2 module, the SM3 module and the SM4 module to carry out corresponding data processing according to the information sent by the sender A, and sends the processed data to the sender A through the communication module. According to the invention, the security defect that the data integrity and identity verification are not carried out when the receiver receives the data is overcome.

Description

technical field [0001] The invention relates to the field of data processing, in particular to an audio data processing device and processing method. Background technique [0002] In today's era, people have to actively or passively receive and send information every day. For the information carrier form of audio, it also contains a lot of information. For some paid music resources or reading audio of books, if leaked, it will also infringe the copyright of the original author, cause economic losses, and is not conducive to social atmosphere; for some important audio involving state secrets or internal company information, it is necessary to conduct Protection of information; even in the context of military warfare, once information is obtained by the enemy, it is tantamount to defeat before the battle. It can be seen how important it is to protect information in some application scenarios with extremely high security requirements. Therefore, in order to protect audio inf...

Problems solved by technology

Because in the process of data transmission, data transmission is not safe, there is a danger of data being tampered with and false information sent by a third party, so the subsequent data processing operations are carried out without verifying the received data, etc. invalid and unsafe
